Docker Examples

Basic Example

The following is a basic example of using rpxy with docker-compose, serving whoami container as a backend application.

You can run the following commands to start the containers.

% docker-compose up -d -f docker-compose.yml

Specifically, the following is the configuration:

rpxy listens on port 80 and 443
- HTTP/1.1, HTTP/2, and HTTP/3 are supported.
- HTTPS redirection is enabled.
- TLS Certificates are automatically obtained from Let’s Encrypt.
whoami listens on port 8000, which is not exposed outside.
rpxy forwards requests to whoami container based on the hostname and TLS SNI.
rpxy logs are saved in ./log directory.
rpxy cache is saved in ./cache directory.
rpxy ACME certificates and private keys are saved in ./acme_registry directory.
rpxy configuration is saved as ./config/rpxy.toml

`docker-compose.yml`
